Archbishop Fisher's significant archiepiscopate reflected the central issues of his time and place. It was Fisher who oversaw an immense programme of reforms which effectively recast the institutions of the Church of England for generations to come. It was Fisher who proved to be the essential architect, politician and diplomat behind the creation of a worldwide Anglican Communion. His determination to promote the development of relations with other churches produced a vital contribution to the cause of ecumenism, which culminated in his momentous meeting with Pope John XXIII.
